No only bike accessories made from vegetable-tanned leather and stainless steel.
The Frera. Leather.
The most important: choose a color to match the paint on the bike. I decided to make classic beige leather that will be beautifully getting old. Handlebars cover with 1,5 mm vegetable-tanned leather and a little bit of cork for anti-vibration. Roll's with simple recover and transport bag you already know.
